Crankshaft REF connector color code

NB8A (however I'm sure this is across the board)
There are three wires in the grey crankshaft REF connector that is mounted on the front of the timing cover.
One side of the plug is the engine wiring loom and the other side goes to the REF switch.

The REF switch side has Black, Red and Blue wires
Can someone tell me what wire colors from the wiring loom connect with the Black, Red and Blue wires at the connector.

Any help would be appreciated.

Thanks for the reply Fatty 8)

Madraki's diagrams (and the workshop manual) only show the wiring harness colors. They dont have the colors of the wires going from the wiring harness plug (on the front of the motor) to the hall sensor mounted next to the crank pulley.

Seems like that info can only come from someone actually looking at the plug and noting which wire color connects with which wire.

Hopefully someone with a NB8A will brave the cold and look for me

All sorted? My NB8A engine sits on the garage floor, makes it easy to check these things.

Okibi, could you have a closer look as one of the red/whites that AZNTieN kindly listed should be grey/white. It would save me having to open up the loom again to find the old wiring. Cheers

As I no longer have that part of the original loom in place I'm connecting into this plug with my new loom but I need to know which wires are what (+ - signal)

Looking at the top of my engine in the car it would appear


Sensor - Loom

Black - Black with blue stripe
Blue - Greyish
Red - White with red stripe

Excellent Okibi. The last two pics and the description was what I was after. I am indebted to the forum. Cheers
